Answer:
Medium pizza is 62.83 square inches greater than smaller pizza.
Step-by-step explanation:
Given:
Diameter of smaller pizza = 8 inch
Diameter of medium pizza = 12 inch
We need to find how much greater in area is medium pizza than the small pizza.
Solution:
First we will find the are of both the pizza;
Now we know that;
Radius =
Diameter
Radius of Smaller pizza = 
Radius of Medium pizza= 
Now pizza is in circular shape so we will apply area of circle to find the area of the pizza.
Area of circle is π times square of the radius.
framing in equation form we get;
Area of Smaller Pizza = 
Area of Medium Pizza = 
Now to find Difference we will subtract Area of Smaller Pizza from Area of Medium Pizza.
So we can say that;
Difference = 
Rounding to nearest hundred we get;
Difference = 
Hence Medium pizza is 62.83 square inches greater than smaller pizza.
